China's Galbot robot takes on tennis star Zheng Jie in world's first human-robot match_我的网站

A humanoid robot went head-to-head with a former tennis champion in what was billed as the world's first human-robot tennis singles match, showcasing its ability to move, return shots and even recover from a fall during a high-intensity rally.
The match took place on Saturday as the second World Humanoid Robot Sports Games got underway. On one side of the net was Chinese tennis star Zheng Jie; on the other was a humanoid robot developed by Galbot.
The event kicked off with an entertaining mixed doubles match, in which the robot Xingzai impressed audiences with its nimble movement. It quickly moved forward and backward as needed and worked seamlessly with its human partner, with the pair adopting a complementary front-and-back formation against their opponents.
The spotlight then turned to the singles match between Zheng and the humanoid robot.
The robot held its own in rallies, trading both forehand and backhand shots with Zheng. When Zheng raised the difficulty by sending over a high, looping ball, the robot was pushed from side to side and eventually lost its balance, landing flat on its back. But it quickly recovered, adjusting its posture and getting back on its feet within seconds.
The robot also showed a surprising ability to read Zheng's slices and spin. When Zheng began moving it deliberately from side to side and from front to back, the robot responded with an impressive lunge that drew cheers from the crowd.
Throughout the match, the robot performed actions including bending its knees, tossing the ball and rotating its body entirely on its own.
The robot's serves surpassed 100 kilometers per hour, leaving it only fractions of a second to react, yet it rarely faltered under the pressure.
AlphaGo defeated South Korean Go champion Lee Sedol 10 years ago, demonstrating the power of AI in the digital realm. A decade later, a Chinese humanoid robot is stepping onto the court alongside an elite tennis player.
If AlphaGo showed that AI could master the digital world, the tennis match offered a glimpse of how AI-powered robots are beginning to withstand the demands of the physical world, experts said.
For the first time, AI was no longer confined to code. The robot ran, swung its racket, competed in real-time — and even picked itself up after falling, before carrying on with the match.
。    Swiss start-up Climeworks AG says construction of its second large-scale direct air capture plant will be completed in Iceland in 18-24 months and will be able to suck 36,000 tonnes of CO2 out of the air each year.,Construction on the plant is set to begin on Wednesday and will be the largest carbon dioxide capture plant in the world, surpassing the company’s current plant by 10 times. That plant is currently the world’s largest.,The new plant will contain roughly 80 blocks of fans and filters that will extract CO2 from the air. Another company, Carbfix, will then mix the CO2 with water and store it underground where a chemical reaction will turn it into stone.,Climate Change is Causing Worldwide Sleep Loss, Study Finds21 May, 02:32 GMT,The 36,000 tonnes of CO2 the $627 million facility will suck from the air will only offset a tiny fraction of the more than 36 billion tonnes of CO2 emissions produced annually. But the company says it represents a large leap for the technology and exponential growth of it may be necessary for the world to meet its climate goals.,Currently, there are 18 carbon capture facilities in the world, with another set to be built by U.S. oil company Occidental, planned to launch in 2024. That plant will be capable of capturing 1 million tonnes of CO2 annually.,Unfortunately, the process to put carbon into the ground can cause some carbon emissions itself. Carbfix will use geothermal power to perform that service for the Climeworks factory. While geothermal power is much cleaner than traditional fossil fuel plants, it is not without some carbon emissions.,While climate scientists say that carbon-capturing plants are likely a necessary part of fighting climate change, they should not be seen as a silver bullet. Reducing emissions is still considered the best way to head off climate change.。
